Introducing 11 O'Clock Stock!
This is what The Motley Fool is all about. Starting Monday, the Fool will present a new stock idea each weekday, for free, on Fool.com. It's 50 great stocks across 50 days, and the Fool is getting in on the action by investing $50,000.

"Why invest now? Investors have given up faith in the market," writes Fool co-founder and CEO Tom Gardner in introducing the endeavor. "Worse yet, the crash has made people lose faith in their own abilities. [Fellow Fool co-founder David Gardner] and I decided to challenge our team of analysts to prove that investing in the market is still exciting, that there are still great stocks providing amazing returns."

The Android Phones That Should Really Frighten Apple
Perhaps you invest so that you can be a wealthy American. But that doesn't mean you should always think like a wealthy American.

Fool Eric Jhonsa takes a look at the Racer, a new Android phone from China's ZTE. It's less impressive than an Apple (Nasdaq: AAPL) iPhone, but more importantly, it's cheaper. The Racer is built on the Android platform developed under Google's (Nasdaq: GOOG) leadership.

"The goal here is to appeal to hundreds of millions of wireless users worldwide who would love to get their hands on a smartphone running an advanced operating system like Android, but who can't afford the headline-grabbing models," writes Eric.

A Baltic Cloud on the Horizon
The Baltic Dry Index helps investors figure out the big picture by keeping tabs on how much shipping companies are charging their customers. "Historically, it's been a great indicator of general economic strength," writes Fool Jordan DiPietro, "but now, that premise seems less certain."

Investors can't take anything for granted.

The BDI has dropped about 60% in the past month, and companies including DryShips (Nasdaq: DRYS) and Excel Maritime Carriers (NYSE: EXM) have seen their share prices plummet in recent months. Weak demand caused by international economic problems played a role, but Jordan notes that investors also need to consider the effect of an increase in ships.
